LEAF-TU RN ER.

SPECIFICATION forming part of Letters Patent No. 627,608, dated June 27, 1899.

Application filed ll'uly 1 5, 1 8 9 8.

To ctZZ whom it may concern Be it known that I, JAMEs E. WIZE, a subject of the Queen of Great Britain, residing at Rossland, in the Province of British 00- lumbia and Dominion of Canada, have invented certain new and useful Improvements in Leaf-Turners, and I do hereby declare the followingto beafull, clear, and exact description of the in vention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to leaf-turners intended particularly for use in connection with sheet or other music on pianos, organs, musicstands, or the like.

It is my object, among others, to construct such a'leaf-turner as an attachment complete in itself and adapted to be readily attached to or detached from the music support or shelf and to so construct the attachment that the music-turning arms can be easily and quickly adjusted to books of different thicknesses, so that the arm-pivots will always be in proper relation to the back or hinge of the music-book, and to generally simplify and improve such music-leaf turners.

With such objects in view the invention embodies the parts, arrangements, and combinations thereof hereinafter described, and particularly set forth in the claims.

In order that the invention may be more fully understood, I have shown in the accompanying drawings means for carrying the same into practical effect, but desire it to be understood that I do not limit my improvements in their useful applications to the particular construction which for the sake of illustration I have therein delineated.

In the drawings, Figure 1 is a plan view of a music-leaf turner embodying my improve ments. Fig. 2 is a vertical sectional View thereof on the line 2 2 of Fig. 1, and Fig. 3' is a front elevation of the leaf-turner shown in Fig. 1.

Referring to the drawings, wherein like ref erence-letters designate corresponding parts in the several views, Arepresents a base-plate having at the rear thereof an upwardly-extending flange or plate B, forming a back or stop for the music which it is intended to support upon the base-plate A. This base-plate A is intended to be detachably supported on Serial No. 686,081. (No model.)

the supporting ledge or shelf of the musicholder. As a means fordetachably securing the base-plate t0 the music-support I preferably secure to the base-plate, conveniently at each end thereof, a spring clip or clasp O. If desired, these clips may be provided with a to prevent marring of the music-support in case the latteris constructed of material which is easily defaced.

D D represent swinging arms pivotally connected to the base-plate, so as to swing horizontally from side to side thereof. At or near the outer ends of the arms are secured, and preferably by swiveling the same on pivots cl, clamping means for attachment to the musicleaves, which means are shown in the draw ings as being spring clips or fastenings E, it being my intention. to employ any suitable or desirable form of fastening means. If desired,the arms can be made of diiferent length,

the base-plate and so that they can be readily and easily grasped to turn the leaves.

It often happens that a book of considerable thickness is employed in connection with the device, and in order that the pivot connection for the arms maybe adjusted to suit the different thicknesses of books, so that it will always bear the proper'relatioii to the leaves to avoid danger of tearing or buckling the same in operation of the device, I make use of the following construction: F is a flat plate pivoted at f to the base-plate A and having at its opposite or free end a pivot G, on which the several arms D of the turner are pivoted. The base-plate A is provided with a slot H to permit the swinging of the plate F and pivot G in toward the back of the base-plate A. On the base-plate, at the opposite side of the slot to the pivot f, is pivoted at j a second plate or link J. This plate J has in its free or swinging end an elongated slot 70, in which the pivot G works or slides. By this arrangement of links it will be seen that the pivot G is free to be moved in or out toward or from the plate A and is limited in its' movement by the slot 70. In order to strengthen or brace the links, I have shown a second link J, secured to and movable with the link J and similar to such link, having an elongated slot 70, in which the pivot G also covering or bearing-surface of soft material so that the spring-clips E may lie close in to works. It will be observed that the link F is pivoted on top of the base-plate, whereas the links J and J are pivoted on the under side of the base-plate. By so arranging the links very light stock or metal may be employed and the arms D still have a sufiiciently firm support and at the same time will offer no material obstruction to catch on or knock against the book or music resting on the base-plate.

The base-plate and links supporting the pivot for the arms D are all preferably made of very light sheet metal.

From the foregoing description it is believed that the use and operation of the device will be readily understood.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1-. In a leaf-turner, the combination of a base-plate, and means for securing the same to a support, a plurality of arms each provided with means for attachment to the music-leaves, a pivot for said arms, and a support for said pivot movable toward or from the base-plate.

2. In a leaf-turner, the combination of a base-plate and means for securing it to a support, a plurality of arms having means for attachment to the leaves, a pivot for said arms, a plate pivoted to the base-plate to which said pivot is secured, and a second plate secured to the first plate and provided with an elongated slot in which said pivot works;

3. In a leaf-turner, the combination of a base-plate having intermediate its ends a slot, a plate pivoted to the base-plate at one side of said slot and on top of the base-plate,a plate pivoted on the under side of said base-plate at the opposite side of said slot, a plate J secured to and movable with said second plate, a pivot carried at the free end of the first mentioned plate and working in elongated slots in the other plates, a plurality of arms hinged on said-pivot, and clips one on each arm for attachment to the leaves.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES E. VIZE.
